I'm having trouble connecting to my appserver, I get the following error message:

'NameServer Communications Failure - System.Net.Sockets.SocketException: A blocking operation was interrupted by a call to WSACancelBlockingCall
   at Progress.SupportClass.UdpClientSupport.Receive(UdpClientSupport tempClient, PacketSupport packet)
   at Progress.NameServer.Client.NameServerClient.receiveResponse(Int32 responseCount, String applicationService) (8230)'

This is an Network/AppServer issue, the Connection details for your server is failing to connect to the AppServer via the Nameserver. 

This could be network of firewall issues but it could also be related to the Progress/OpenEdge Name Server 

The Name server sometimes can have issues with connection, it may need the Progress Nameserver or Admin server to be restarted.

An Alternative method is to ""Connect Directly to the AppServer. this can be set using a checkbox on the Connection Details screen for your system

You would need the the actual AppServer Port Number to complete the direct connection setup.
